Eth Zurich: The Latest Architecture and News

Dübendorf, Switzerland is something of hallowed ground for architectural technologists. There, on the shared academic campus of the Swiss Federal Laboratories for Materials Science and Technology and the Swiss Federal Institute of Aquatic Science and Technology, public university ETH Zurich has conducted nearly a decade of engineering and construction experimentation at the ever-evolving NEST research building. In August, ETH Zürich unveiled its latest extension of the building, HiLo (short for high performance-low emissions)—a two-story modular addition to the chameleon structure that harnesses medieval building principles and contemporary digital methods to raise the bar for more sustainable applications of concrete.

With the aim of generating a significant impact on the responsible and sustainable consumption of resources and energy in the construction industry, ETH Zürich in collaboration with FenX AG is using foam 3D printing (F3DP) to manufacture geometrically complex formwork for the construction of special elements in concrete.

In order “to help architects and students to get to know the best International Master’s programs available”, the Best Architecture Masters (BAM) has established its annual list of top postgraduate architecture curriculums. Based on the QS Ranking by Subjects – Architecture / Built Environment, for the 2021 edition, 22 Universities were selected to be evaluated, by an Expert Committee, formed by 15 professors from all over the world.

In 2021, the Harvard Master in Architecture II continued to lead the ranking, and Colombia maintained second place with its Master of Science Degree in Advanced Architectural Design. TU Delft in the Netherlands took on the third position, becoming the best in Europe while Tsinghua University in China followed in the fourth position, becoming the best in Asia. The Master in Architecture of the Pontificia Universidad Católica in Chile occupied the 15th position and was named the best program in Latin America.

Every year in March, the QS World University Rankings reveal the top universities to study each profession, covering 51 different subjects. Grading schools based on academic reputation, employer reputation, and research impact, the annual QS- Quacquarelli Symonds has unveiled that for the second year in a row, in the 2021 Architecture/ Built Environment division, the Massachusetts Institute of Technology (MIT) is still in the first position.

Like most functions in recent months, this year’s Digital FUTURES, which is held annually since 2011 at Tongji University in Shanghai, had to move online due to the pandemic. The organizers took this as an opportunity to give the event a global dimension, turning the festival into what they rightfully call the most significant worldwide event for architectural education ever staged, with a 24/7 display of workshops, lectures and panel discussions involving some of the most prominent architects and educators. Here is an overview of the festival, together with a selection of lectures from Digital FUTURES World.

Digital fabrication is a manufacturing process that uses a machine controlled by computers. This method has sparked the interest of architects and product designers, as it opens the door to new possibilities in terms of solving complex processes and new approaches for mass construction.

The annual QS- Quacquarelli Symonds ranking for top universities has been unveiled. Based on academic reputation, employer reputation, and research impact, the ranking highlights every year the best universities for each profession. In the 2020 Architecture/ Built Environment division, the list reveals that the Massachusetts Institute of Technology (MIT) is back on top.

MVRDV in collaboration with Airbus, Bauhaus Luftfahrt, ETH Zurich, and Systra, is developing a plan for the future of Urban Air Mobility (UAM). The investigation tackles the integration of “flying vehicles” into our urban environments and envisions a comprehensive mobility concept.

With the intention of maximizing available space and avoiding steep construction costs, researchers from ETH Zurich’s Department of Architecture have devised a concrete floor slab that with a thickness of a mere 2cm, remains load bearing and simultaneously sustainable. Inspired by the construction of Catalan vaults, this new floor system swaps reinforced steel bars for narrow vertical ribs, thus significantly reducing the weight of construction and ensuring stability to counter uneven distributions on its surface.

As opposed to traditional concrete floors that are evidently flat, these slabs are designed to arch to support major loads, reminiscent of the vaulted ceilings found in Gothic cathedrals. Without the need for steel reinforcing and with less concrete, the production of CO₂ is minimized and the resulting 2cm floors are 70% lighter than their typical concrete counterparts.

ETH Zurich has unveiled details of “Concrete Choreography,” an installation recently inaugurated in Riom, Switzerland. The installation presents the first robotically 3D printed concrete stage, consisting of columns fabricated without formwork, and printed to their full height in 2.5 hours. The process is expected to greatly improve the efficiency of concrete construction while achieving the fabrication of complex components.

ETH Zurich, working in collaboration with Zaha Hadid Architects Computation and Design Group (ZHCODE) and Architecture Extrapolated (R-Ex) have unveiled a 3D-knitted shell serving as the primary shaping element for curved concrete structures.

The “KnitCandela” prototype represents the first application of this technology at an architectural scale, a five-tonne concrete structure on display at the Museo Universitario Arte Contemporaneo in Mexico City.

The advent of robotics in the creative and construction industries has led to an amazing revolution, changing not just how things are designed and made, but also transforming knowledge cultures, politics and economics that surround them. As such, the ROB|ARCH 2018 conference – hosted by the NCCR Digital Fabrication and ETH Zurich – will continue this path, developing and revealing novel insights, applications and impacts of this transformation within the scientific, creative, and entrepreneurial domains, including, for example, architecture, structural design, civil and process engineering, art and design, and robotics. A particular focus lies upon cross-disciplinary approaches and applications, providing state-of-the-art knowledge, techniques and methods of robotics not just in individual areas of exploration, but also beyond. These ideals aspire to complement the transformation processes of emerging robotic research and applications, and to redefine cross-disciplinary work in an era of global digitalisation and knowledge transfer. Key topics and issues of ROB|ARCH 2018 include autonomous control systems, advanced construction, collaborative design tools, computerised materials and structures, adaptive sensing and actuation, on-site and cooperative robotics, machine-learning, human-machine interaction, large-scale robotic fabrication and networked workflows.

Complex designs often require bulky structural systems to support imaginative forms. But 3D printing technology has begun to provide unlimited architectural potential without compromising design or structural durability. Researchers at ETH Zurich, under the leadership of Benjamin Dillenburger, have now developed an innovative 3D sand printing technique that allows for quick molding and material reuse.

They have used this technique to create a formwork to fabricate an 80 square meter lightweight concrete slab at the DFAB House, the first and largest construction of its kind. The “Smart Slab,” which carries a two-story timber unit above it, merges the structural durability and strength of concrete with the design liberation of 3D printing.

Digital technology has broken into the timber construction scene at ETH Zurich, where a research team is using programmed robots to construct load-bearing timber modules. These modules are being used to stabilize the top two levels of their DFAB HOUSE project, a three-story residential unit located in Dübendorf, which aims to bring a variety of digital construction methods together under one roof.
